Potato Rösti

30g butter 1 onion, chopped
3 medium potatoes, coarsely grated

Squeeze the grated potato before cooking to reduce the amount of water and starch. Heat the butter in a pan, add onion and cook until soft. Add potatoes and stir until they are sticky; cool. Shape teaspoons of potato mixture into rounds with wet fingers and flatten. Heat some butter and oil in a pan and cook rösti for 3-5 minutes on each side until browned.
